Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Security management has reduced ransomware risk and now protects cloud workloads efficiently
The best features that Barracuda WAF-as-a-Service offers are an intuitive centralized dashboard, allowing us to manage policies, Internet protocol servers, antiviruses, anti-DDoS attacks, and traffic shaping across multiple sites. This feature enables seamless scaling of our environments, especially as we work within Amazon Web Services. Additionally, real-time threat intelligence helps us to detect threats in real-time. Another major feature I love is application control and VPN support, providing granular visibility and protection without needing separate appliances. The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place. The real-time threat intelligence is an advanced feature helping us track real-time attacks, such as anti-DDoS attacks, ransomware, or viruses that can compromise system integrity. Through the intuitive centralized dashboard, we can manage policies and set rules, assisting us effectively.

Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"Does a good job preventing web application attacks."
"Technical support has a very fast response time and they are helpful."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"It is a SaaS solution unlike much of the competition."
"It protects web applications efficiently."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."
"I like its ability to identify known attacks, including DDOS attacks, because application attacks are evolving all the time and, when it comes to software-as-a-service, we need to have software that knows about all the latest attacks and also protects against major unknown attacks."
"The solution can be used for threat prevention or as a cloud-to-cloud backup system"
"It provides an ease of policy management."
"The solution covers a lot of major protection or threat management functions in the feature itself."
"Barracuda WAF-as-a-Service has positively impacted our organization by reducing cyber threats like ransomware and phishing by ninety-five percent."
"Barracuda WAF-as-a-Service's real-time attack detection feature has improved our customers' threat response strategies significantly."
"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."
"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."
"It is a stable solution."
"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"The solution is very scalable; it is one of the most important features, and you can also expand resources and features as well."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."
"As a system, it's very effective at blocking potentially malicious items."
 

Cons

"The product can improve by having more multitenancy capability, which is currently not available."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"They have some limitations with third-party integrations."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The stability of the product is an area of concern where improvements are required."
"The price of their licensing model is a bit steep, and the pricing and SIEM integration sometimes create challenges, and we need to get professional help with those areas."
"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."
"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."
"We found it a bit slow when accessing it through the web browser."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."
"I think the pricing needs some tweaks."
"We had an issue when securing the web applications for DDoS protection."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"I don't really use it and therefore can't speak to areas of improvement."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"The dashboard is not accessible on occasion."
"The signature updates could be faster."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
 

Pricing and Cost Advice

"It is not too pricey."
"It starts at $20 and can easily go up to $200 monthly"
"We pay $210 per month for CloudFlare WAF."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The product is expensive but it offers flexible pricing. It could be affordable."
"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."
"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"We are satisfied with the pricing."
"Imperva Web Application Firewall is expensive."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"The price is high compared to other solutions like FortiWeb."
"The tool is expensive."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"It is expensive."
